Sidebar as secondary navigation
On the left of the CRM there's a sidebar showing activity in chronological order. If you log in you land on the Dashboard in which the sidebar would show all types of activity. E.g. (new) messages, invoices, clients and so on. When you would go to the messages page it would only show you the latest messages.
A user's attention is drawn by a blue triangle with icons on the right side of a row. For example; an invoice that's due shows a blue corner with a tiny piggybank icon.
To guide the user only to those elements that are important, we used soft monochromatic colored icons for the normal state of a row. Hovering a row shows much more contrast both in text and icons.
